Description
I discuss the entanglement entropy for a free scalar field within a spherical region in various gravitational backgrounds (flat, de Sitter and anti-de Sitter space, the Einstein universe). In the first part I focus on the structure of the divergences. Universal coefficients are determined for ultraviolet and infrared divergent terms. In the second part I discuss the use of the finite part of the entropy for the calculation of a c-function in 1+1 dimensions and an a-function in 3+1 dimensions.
